Phoenix Contact 1898648 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1898648 is a 3-position terminal block header with male pins, shrouded design, and 0.200" (5.08mm) pitch for vertical through-hole mounting. This component is part of the COMBICON EMSTBV series and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from the active COMBICON product lines are available to maintain design compatibility and ensure continued supply chain availability.

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1898648 are selected based on strict electrical and mechanical compatibility criteria. The following parameters must match or exceed the main part specifications:

• Number of Positions: 3 (exact match required)
• Pitch: 0.200" (5.08mm) (exact match required)
• Header Orientation: Vertical (exact match required)
• Type: Header, Male Pins, Shrouded (4 Side) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Current - IEC: Minimum 12A
• Voltage - IEC: Minimum 320 V
• Current - UL: Minimum 12 A
• Voltage - UL: Minimum 300 V
• Material Flammability Rating: UL94 V-0 (exact match required)

The substitute parts listed below meet these criteria and are sourced from active Phoenix Contact COMBICON product series, ensuring long-term availability and design continuity.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts meet the core electrical and mechanical requirements of the Phoenix Contact 1898648. Selection between them depends on specific application constraints:

Phoenix Contact 1777086 (COMBICON MSTBV Series): This substitute maintains identical electrical ratings (12A IEC, 630V IEC) and mechanical dimensions (contact tail length 0.154", insulation height 0.472") to the main part. It features solder termination instead of press-fit and is ROHS3 compliant with active product status, ensuring long-term availability. The green housing color matches the original part.

Phoenix Contact 1792740 (COMBICON CCV Series): This substitute meets minimum electrical requirements (12A IEC, 400V IEC) with a reduced UL current rating of 10A. It features solder termination, a shorter contact tail length (0.102"), and Liquid Crystal Polymer (LCP) housing material instead of PBT. The black housing color differs from the original. This part includes a locking ramp feature and is RoHS compliant with active product status.

Both substitutes are classified as active products with unlimited moisture sensitivity levels and are suitable for applications requiring long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1777086 directly replace the 1898648 in existing designs?

A: The 1777086 maintains identical electrical ratings (12A IEC, 630V IEC) and mechanical dimensions (contact tail length 0.154", insulation height 0.472"). The primary difference is termination style: the 1898648 uses press-fit termination while the 1777086 uses solder termination. PCB design modifications may be required to accommodate solder termination instead of press-fit.

Q: What are the key differences between the 1777086 and 1792740 substitutes?

A: The 1777086 maintains the original contact tail length (0.154") and PBT housing material with green color. The 1792740 has a shorter contact tail length (0.102"), LCP housing material, and black color. The 1792740 also has a reduced UL current rating of 10A compared to 12A for the 1777086. Both use solder termination.

Q: Are both substitute parts RoHS compliant?

A: Yes. The 1777086 is ROHS3 compliant, and the 1792740 is RoHS compliant. Both meet environmental compliance requirements for electronic components.

Q: What is the impact of the different housing materials (PBT vs. LCP)?

A: The 1898648 and 1777086 use Polybutylene Terephthalate (PBT), while the 1792740 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability ratings. Material selection may affect thermal performance and mechanical properties in specific operating environments.

Q: Can the 1792740 be used in applications requiring 12A current at UL ratings?

A: The 1792740 has a UL current rating of 10A, which is below the 12A requirement of the original 1898648. Applications requiring 12A at UL ratings should use the 1777086 substitute instead.

Q: What is the significance of the contact tail length difference?

A: The 1898648 and 1777086 have contact tail lengths of 0.154" (3.90mm), while the 1792740 has 0.102" (2.60mm). This difference affects PCB hole depth and solder joint geometry. Verify PCB design compatibility before selecting the 1792740.
